Furniture Office Chair Standard

The standards for furniture office chairs mainly involve aspects such as height, seat dimensions, seat depth, seat width, and the vertical drop between the seat and the desktop. Details are as follows:

Height: According to national standards, the height range of adult office chairs is 40 to 50 centimeters, as explicitly required by GB/T 3976-2014. For most adults, the commonly used height for men is 43 centimeters, while women have a corresponding benchmark height, though the specific value is not clearly defined. It is best for office chairs to have an adjustment function. Mainstream pneumatic rod adjustments offer a wide range, suitable for people of different heights. For example, individuals who are 160 centimeters tall are recommended to adjust the chair height to 42 to 43 centimeters, those who are 165 centimeters tall are suitable for 43 to 45 centimeters, and those who are 170 centimeters tall are best adjusted to 45 to 47 centimeters. When adjusting, ensure that both feet can rest flat on the ground when seated, with the thighs and lower legs perpendicular to each other. This is the key criterion for determining whether the chair height is appropriate.

Seat dimensions: The width of fixed-style seats is generally between 40 and 45 centimeters, but it is preferable to choose adjustable models, with a width range typically from 38 to 48 centimeters. Adjustable designs can better accommodate users of different body types, preventing discomfort from seats that are too narrow or too wide during prolonged sitting.

Vertical drop between the seat and the desktop: The seat and the desktop need to maintain a vertical drop of 25 to 30 centimeters. This design ensures that arms can be placed naturally without excessive lifting or drooping, thereby reducing fatigue in the shoulders, neck, and arms and enhancing office comfort.

Seat depth and width: The seat depth should be sufficient to support the entire buttocks, preventing pressure concentration due to the buttocks being suspended. The seat width should ensure that users can move their bodies freely, avoiding restricted blood circulation or reduced mobility due to cramped space.

Backrest: The backrest should precisely fit the curve of the human waist, ideally being able to “just support the lower back” to provide effective support for the lumbar spine. This design can disperse pressure on the waist, preventing issues such as lumbar muscle strain or lumbar disc herniation caused by prolonged sitting.
